Offshore Production Platform Deck Decommissioning and Removal
The decommissioning of the deck processing equipment can now commence. This consists of gas - freeing of all pipelines, vessels, process pumps gas and air compressors.
All diesel and water storage tanks should have been pumped dry at initial shutdown, but these should be rechecked and gas-freed. Power and compressed air should be supplied using temporary power units.
Once again the production headers, HP and LP separators, oil export pumps and associated pipework will all require earmarking for the nuclear facility.
Once this has been completed, the deck can be removed in pieces, usually by modules small enough to safely lift and transport on barges to licensed shoreside facilities.
Specialist equipment such as wireless and radar, lifeboats, lifebuoys, fire extinguishers, power generation units and pedestal cranes, may be reconditioned and sold for reuse.
A good clean-up, and preservation (see article on offshore equipment preservation) along with the maintenance records and the hours run for diesel power generators and cranes will greatly enhance the asking price of these items.
